一、前言高频感应耦合等离子体(以下简称ICP)作为优良的蒸发汽化源、原子化源(原子化器)、激发源及离子源而正在发射光谱分析(以下简称AES)中大量应用。然而,由于ICP产生的各种谱线非常多,对于ICP-AES分析,为使分析元素的光谱线分离,必须使用高分辨率的单色器,通常,由于光谱线的重叠或背景等产生的光谱干扰已成为重大的难题。原子荧光光谱分析(以下简称AFS)自1964年由Winefordner
I. INTRODUCTION High-frequency inductively coupled plasma (hereinafter referred to as ICP) is being widely used in emission spectrometry (hereinafter referred to as AES) as an excellent evaporation vaporization source, atomization source (atomizer), excitation source and ion source. However, due to the large number of lines generated by ICP, it is necessary to use a high-resolution monochromator for ICP-AES analysis in order to separate the spectral lines of the analyzed elements, usually due to overlap of the spectral lines, background, etc. Spectral interference has become a major problem.
